Abstract

The purpose of this research was to obtain estimation models for the time duration of maintenance and repair activities performed at selected sections of the Facilities Department at the University of Puerto Rico in Mayaguez (UPRM) and design a database using these models. These sections were Electricity, Refrigeration and Plumbing. Tasks performed by these sections were divided into activities and then classified as either constant or variable. The estimation models were a result of a combination of the times of both constant and variable activities. The time estimates database allows the user to estimate the total man- hours required to process a work order and obtain a Productivity Index (PI). A survey was conducted in the studied sections to determine opportunities for productivity and methods improvement taking into consideration the search for materials, material handling equipment, transportation, the setup activity, and the repair or service activity.
